IMPROVEMENT IN WATER-ICLOSETUTANKS, 1520.

Specification forming part of Letters Patent No. 180,059, dated July 18,1876; application filed May 18, 1876.

To all whom it may concern:

Be it known that we, STEWART PETERS and WILLIAM DONALD, of Glasgow,Scotland, have in ented certain Improvements in VVater- Closet Tanks,and Apparatus for the Supply and Discharge of Liquids; and we do herebydeclare the following to be a full and correct description of the same,reference being bad to the accompanying drawings, in which Figure l is avertical section of our improved apparatus as applied to what are knownas hopper closets. Fig. 2 is a plan or top view of the same. Fig. 3 is avertical section of our apparatus slight-1y modified, so as to beapplied to a pan or valvecloset.

The same part is marked by the same letter of reference wherever itoccurs in the drawings.

The object of our invention is to simplify the construction of theworking parts, and to prevent the waste of water, by limiting the amountof the discharge and after-flush.

The nature of our invention consists in providing the water-tank with asiphon, operated by a lever under control of the closet-handle, todeliver to the closet a fixed supply of water, with or without anafter-flush, as may be required; and, in combination with saidapparatus, a self opening and closing faucet, provided with a lever andball-float, all constructed and operating substantially as hereinaftermore particularly set forth.

In the accompanying drawings, A marks a small tank, made of cast-iron orother suit able material. From the bottom of the tank projects upwardthe conical tube D, made, preferably, of copper, and extending above thewater-level. Over this tube is suspended a copper cap, E, hung t0 thecistern-lever F, which has its fulcrum in a stud attached-to the side ofthe tank, and is connected by chain or rod M with the closet-handle N.(See Fig. 3.) A very small hole, E is bored in the top of cap E, permitsthe escape of airfrom the cap, and allows the water in the space E between the cap and tube D, to attain the same level as that in the tankA.

H is the service-pipe, provided near its junction with the closet withthe ordinary siphontrap H l is the supply-pipe, connected with 'thestreet-main or other source of supply. It has V a valve or faucet, J,connected with a lever, L, provided with a ball-float, K, on itsextremity. This float rises and falls in a chamber,

tube D, and the shorter arm of the space between cap E and tube D. Whenonce the siphon is set in action, it will continue running until thewhole of the water in the tank has been discharged, provided the cap Ebe held up; but the action will stop immediately on the cap beingallowed to fall, so that a partial or complete flush may be had, asdesired. The small hole h in the float-chamber B allows the water toescape from that chamber after the contents of the tank have beendischarged. The fall of the ball-float K opens the supply cock J, andthe tank is again filled to a height at which the rise of the ballclosesthe cook.

The foregoing description applies specially to the arrangement shown inFigs. land 2, in which a hoppencloset, without a pan, is to be supplied.7

Fig. 3 illustrates the modification made to supply the after-flushrequired in pan or valve closets after the main flush has stopped. Itconsists of a copper tube, 0, introduced between the tnbe l) and the capE, in the manner clearly represented in the figure. When the maindischarge is in action the space between D and 0 will become filled withwater; and after the cap E has been dropped to arrest the maindischarge,'the water in O escapes through a small hole, a, made in theside of tube l), and supplies the required aftertlush to the pan-closet.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is-
